No, dedicated add-ons are the only type of package management. If you have to have such packages, drop LE, and install Ubuntu with Kodi on auto-start.

It's plug-and-play after pairing.

I wasn't sure how far the boot process went, thanks. So we are still at kernel level. Does it boot with Ubuntu?

So, last night, to test with, I installed Ubuntu on it just to see if it's a driver issue before I gave up. Funny enough same issue. I installed alsa-tools, and alsa-tools-gui, from a post I found somewhere, selected "unconnected pins" and have overridden them with Displayport/HDMI, and it worked.

...

Worst case, if we cannot get LibreElec to work, not the end of the world, I'll just Ubuntu+Kodi it haha!

Can you share that Ubuntu link? I have no clue what "unconnected pins" means here.

And how do you edit cmdline.txt on the FAT32 partition from Libreelec?

Same way as config.txt.

This build seems to be your solution: Simultaneous Audio Output

Set it to log level 2 by using advancedsettings.xml.

When it fails to boot, login by SSH, run pastekodi, and post the resulting URL.

The Moonlight add-on has Steam Link support. There was a bug since LE 11, so you eventually have to try LE 10 or a nightly build.

Thanks!

chewitt Maybe an Embedded DisplayPort (eDP) issue?

I've tried the EDID config

So you've created your own EDID file like this, right?

Sep 20 19:09:07.151062 LibreELEC kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

Make sure your BIOS is up-to-date.

First: JACK is not our problem, because we don't use it on LE. However...

a) I'm not sure whether RPi is capable to handle more than two JACK channels. Maybe overclocking is needed.

b) To rule out processing issues, try a muli-channel JACK setup on a regular X86 PC first.

c) Patchbox OS has a low-latency kernel, and JACK is pre-installed. Try it, they also have a forum.

If you have more questions about JACK, open a new thread at Off-Topic section.

Likely a kernel issue: Cannon Lake PCH cAVS (ALC892) not detected by kernel driver

Please describe the complete wiring of your A/V setup. You've mentioned a connection to TV and VGA. Are both active at the same time?

The successful ALSA configuration on Ubuntu was probably an audio mapping from one DP to the other. You can't have multiple audio outputs at the same time. Maybe the audio is routed to the VGA, not to the TV.

The specs say that you can only use one DisplayPort:

Quote from HP ProDesk 400 G4 Specifications

NOTE: When configurable I/O port has been configured, one DisplayPort might be blocked in select configurations.

Is that true for your setup?

Quote from Pruts

But I am so in experienced, that my pin 5 and 6 probably are 35 and 36

Pin 5 is GPIO 03, pin 6 is Ground (same height, but the other column).

You'll find diagrams on the internet about pin vs. GPIO numbering.
